Kev siv tau zoo ntawm S890QL (thiab nws cov GB sib npaug Q890E Q + T) hauv kev tsim kho yog qhov tshwj xeeb tshaj plaws, tshwj xeeb, thiab yuav luag tsis hais txog "kev tsim vaj tsev." Nws daim ntawv thov yog cov tswv yim thiab kev ua tau zoo- tseem ceeb, txwv rau cov khoom siv hluav taws xob loj tshaj plaws uas nws cov nqi astronomical (khoom siv + fabrication) yog qhov tsim nyog los ntawm kev tsim cov qauv tsim uas tsis tuaj yeem ua tau.
Ntawm no yog qhov kev tawg ntawm nws qhov tseeb siv tau zoo nyob rau hauv kev tsim kho dav dav thiab kev lag luam hnyav engineering.
Lub hauv paus ntsiab lus tseem ceeb: S890QL yog "Enabling Material"
Nws tsis raug xaiv kom txuag tau nyiaj, tab sis los daws qhov tshwj xeeb, tsis yog -kev sib tham tsis sib haum xeeb uas qis dua - qib steels (txawm S690QL) tsis tuaj yeem kov yeej. Nws txoj kev siv yog tswj hwm los ntawm lub hauv paus ntsiab lus: "Peb xav tau lub zog no hauv lub hnab ntawv / qhov hnyav, thiab tsis muaj lwm txoj hauv kev."
Cov cheeb tsam siv tau zoo
1. Sab Nraud Sab Nraud ntawm Super-Cranes Loj
Qhov no yog daim ntawv thov classic thiab tseem ceeb tshaj plaws.
Teeb meem:Hauv telescopic booms rau cranes uas muaj peev xwm ntawm 1000+ tons, sab nraud boom seem yuav raug rau lub sijhawm khoov siab tshaj plaws tab sis yuav tsum yoglightestkom maximize ncav cuag thiab payload. Siv S690QL yuav xav tau cov phab ntsa tuab, ntxiv qhov hnyav hnyav.
S890QL Kev daws teeb meem:Tso cai rau kev tsim ntawm cov thawv sab nraud no- ntu chords nrog lub zog txaus thiab hauv zos buckling tsis kam siv lub thinnest ua tau daim hlau. Qhov no ncaj qha txhais mus rau hauv:
Qhov siab tshaj plaws tau boom ntev thiab nqa qhov siab.
Siab tshaj payload ntawm lub vojvoog ntev tshaj plaws.
Nyob rau hauv txoj kev thauj khoom hnyav txwv rau cov boom modules.
Kev cuam tshuam:Ua kom muaj kev tsim cov skyscrapers, cua turbines, thiab txuas hniav los ntawm kev muab cov cuab yeej nqa tsim nyog.
2. Tseem ceeb heev, muaj kev ntxhov siab ntau hauv cov khoom hnyav mining & Piling khoom
Qhov twg rog yog concentrated nyob rau hauv compact qhov chaw.
Teeb meem:Cov caj npab thiab cov pas txuas ntawm ultra- cov excavators loj, lossis cov hammers cuam tshuam rau pawg tsav tsheb, kev paub dhau los ntsuas ntau txhiab tons. Cov khoom no muaj qhov txwv geometric nruj.
S890QL Kev daws teeb meem:Siv rau pins, txuas caj npab, thiab siab -stress tsev nyob qhov twg tus ntoo khaub lig-sectional cheeb tsam yog kho los ntawm kev tsim, thiab tib txoj kev uas yuav ua rau kom muaj peev xwm yog siv cov khoom muaj zog. Nws withstands huab dynamic thiab cuam tshuam loading.
3. Kev Pabcuam Tub Rog, Kev Tiv Thaiv, thiab Aerospace Ground Support
Qhov twg kev ua tau zoo trumps tag nrho lwm yam.
Tub Rog Tsheb Ncej / Armor:Nyob rau hauv cov tsheb armored siab heev, S890QL tuaj yeem siv rau hauv lub luag haujlwm ntawm cov cuab yeej cuab tam, qhov twg lub nkoj nws tus kheej yog qhov siab - lub zog thauj khoom - cov qauv kabmob, txuag qhov hnyav hnyav rau kev txav mus los thiab kev thauj khoom.
Launch Platform Cheebtsam:Rau lub foob pob hluav taws tso rau sawv ntsug lossis lub dav hlau thauj khoom ntes cov iav, qhov twg cov khoom yuav tsum nqus cov rog loj, tam sim ntawd nyob rau hauv ib qho hneev taw.
4. Kev thauj tshwj xeeb rau kev tsim kho
Hnyav-Trailer Axles thiab Ncej:Rau kev thauj mega-loads xws li refinery modules lossis choj ntu, qhov uas txo cov trailer tus kheej qhov hnyav ua kom muaj peev xwm thauj khoom.
Dab tsi S890QL tsis siv rau (Kev siv tsis zoo)
Nws yogcategorically ineffective thiab txwv tsis pub muaj kev pheej hmoorau:
Txhua lub tsev tsim qauv(kab kab, kab hauv chaw ua haujlwm, yees, chaw ntau pob).
General choj girders.
Txhua yam zoo li qub, tsis yog - hnyav- tus qauv rhiab heev.
Yog vim li cas:
Kev Tiv Thaiv Tus Nqi:Cov khoom siv thiab cov nqi tsim khoom tuaj yeem yog 10-20x ntawm S355 steel.
Overkill:Lub tsev tsim yog yuav luag ib txwm tswj hwm los ntawm kev nruj (deflection) thiab ruaj khov, tsis yog cov khoom siv zog. Lub steel muaj zog tsis pab yog tias koj xav tau lub nqaj tob dua los tswj cov kev co hauv pem teb.
Kev sib txuas npau suav phem:Txuas S890QL cov tswv cuab yog qhov kev sib tw loj. Bolting yuav tsum tau tshwj xeeb 12.9+ qib bolts nrog meej tensioning. Vuam yog qhov txaus ntshai -, txheej txheem kim uas yuav tsum tau muaj PWHT.
Brittle Fracture Risk:Qhov siab dua lub zog, qhov qis dua qhov ductility. Txhua qhov tsis zoo hauv kev tsim, tsim, lossis khoom siv tuaj yeem ua rau muaj kev puas tsuaj loj brittle fracture tsis ceeb toom. Cov npoo kev nyab xeeb yog nruj dua.
Txoj Kev Txiav Txim Siab: Justifying S890QL
Ib tus kws tshaj lij pom zoo S890QL tsuas yog tom qab teb YOG rau tag nrho cov lus nug nram qab no:
Puas yog tus qauv tsim muaj zog tiag tiag - txwv thiab hnyav- tseem ceeb? (Tsis tawv-limited).
Puas yog siv S890QL tso cai rau cov khoom kom haum raws li qhov tsis yog -kev sib tham geometric lossis qhov hnyav? (piv txwv li, thauj qhov ntev, boom seem loj).
Puas yog qhov kev ua tau zoo nce (piv txwv li, nce crane muaj peev xwm / ncav cuag) tsim cov nqi lag luam uas deb tshaj li cov khoom siv / cov nqi tsim khoom?
Puas muaj ib tug fabricator uas muaj pov thawj, ntawv pov thawj kev txawj ntse nyob rau hauv vuam thiab cua sov- kho Q&T steels siab tshaj 800 MPa yield zog?
Puas yog cov khoom siv thauj khoom feem ntau zoo li qub lossis zoo li - nkag siab tsis muaj zog / qaug zog, tsis muaj kev poob siab xav tau?
Fabrication Reality: Tus nqi tiag
Kev siv tau zoo ntawm S890QL yog nyob ntawm kev tsim khoom zoo meej:
Txiav: Only txias txiav (waterjet, machining) raug tso cai. Thermal cutting yog nruj me ntsis txwv tsis pub.
Vuam:Yuav tsum tau ultra-siab- lub zog sib piv consumables, ceev faj ua ntej/post- cua sov, tsis tshua muaj cua sov input, thiab yuav tsum tau Post-Weld Thaum tshav kub kub kho (PWHT).
Kev tshuaj xyuas:Xav kom NDT dav dav (UT, MT / PT) thiab feem ntau CTOD kuaj kom siv tau cov pob txha tawv.
Xaus: Lub Pinnacle ntawm Cov Qauv HlauDaim ntawv thov
Kev siv tau zoo ntawm S890QL hauv kev tsim kho tsuas yog ua kom muaj lub tshuab huab cua tshaj plaws uas tsim txhua yam. Nws yog cov khoom ntawm kev xaiv rau qhov kawg, qhov hnyav- ua kom zoo dua ntu ntawm lub ntiaj teb cov cranes muaj zog tshaj plaws thiab cov pob qij txha hnyav tshaj plaws hauv mega- nplai lub ntiaj teb- cov khoom txav.
Nws tus nqi tsis ntsuas nyob rau hauv tons, tab sis nyob rau hauv lub meters ntawm ntxiv ncav cuag, tons ntawm ntxiv payload, los yog muaj peev xwm ntawm ib qhov project uas nws muab. Nws yog ib qho kev daws teeb meem rau ib qho teeb meem bespoke, sawv cev rau qhov tseeb frontier ntawm qhov twg welded structural steel siv tau. Rau 99.9% ntawm kev tsim kho, nws yog qhov kev xaiv tsis raug thiab txaus ntshai. Rau qhov tseem ceeb 0.1%, nws yog qhov kev xaiv nkaus xwb.
